I don't know which one is better, but we have 3 Shur-Co's on Wilson 41' trailers now. They work just fine. We did have one motor go out unexplainably within 1 yr of install. It was replaced by warranty. Only problem is, you're without tarp 'til you get a motor. We now have a spare motor on the shelf. We think they install easily. Operation seems good irregardles of temperature.

Probably only quirk is if you're using a fob control next to another truck using fob control @ same time, one of your tarps will stop, 'til the other guy gets done. No big deal.

Here's a YouTube we made when we put the 1st one on a couple yrs ago.

Good luck there.
